I honestly didn't mind Curtis and thought of him as replacing Felicity when we saw him in Season 4. If he took her role along with becoming a bit more of a competent fighter, you would have a pretty decent team.

I think he mainly sucks now because he's the worst fighter and he's only somewhat useful when he is Felicity's hacking sidekick

There was even an episode in Season 4 where Felicity questioned their relationship and talked about how it was bad for both her and Oliver. But after an organic pep talk from her mom, all doubt was erased from her mind.

That episode would've been a perfect end without having to kill Felicity

That's what really bothered me about Olicity. In the first two seasons, it's obvious she had a crush on him but he never seemed romantically into her. And his relationship with Sara didn't have any closure, just like his relationship with Laurel at the end of the first season. Both of those just ended out of nowhere when the next season started.

Which is weird because I do remember people criticizing New Vegas before the release of 4. People still liked it of course, but I didn't see much talk of it being the best Fallout ever made until FO4 launched.

Season 4 of Arrow actually has a more hilarious example. In the finale Darhk used his magic to launch Oliver up into the air through the ground to the surface, and Oliver got up just fine when he landed from the fall.

I think a big contributing factor for this is PUBG being nominated for Game of the Year. If people enjoy it, fine. But an unfinished product being next to quality games definitely rubbed people the wrong way.
